INRODUCTION:
HARNESSING LIGHT Light:1.What is Light?It is multidisciplinary subject . This is both art and science. It helps us to see things around us.
2.How does it influence our lives?Bringing the world together.Light effects national defence and many more.

Harnessing Light..
• LASER- “ Light Amplification”- adding energy for tasks such as cutting, heating, burning, or welding.
• Another use cutting of laser beams into femtoseconds- one quadrillionth of a second.

• BIOSENSORS AND SCAFFOLDING : Helps in tissue growth.
• HELPING IN CELL COMMUNICATION: Helps In delivering a large bundle of signals for communication.

• NANOBOTS AND NANODEVICES- To detect malicious cells at early stage.
• HELPS IN PRINTING ELECTRONIC CIRCUITS- using more manageable and less expensive equipment's

POSSIBILITIES AND
CHALLENGES..• Find or make an element that does not
absorbs radiation. • Improvement in Photovoltaic cells that
permits solar energy to provide up to half of world energy needs by the end of century leading to low carbon future.
• Meeting the needs of computing and communication across the world.
• Usage of UV Rays and Gamma Rays for the benefits of mankind.
